Legally Authorized Representative (LAR)
Definition
A person authorized either by statute or by court appointment to make decisions on behalf of another person. In human subject research, an individual or judicial or other body authorized under applicable law to consent on behalf of a prospective subject to the subject's participation in the procedure(s) involved in the research. There are several considerations that must be addressed when the inclusion of an LAR is proposed, such as, whether periodic re-consenting is warranted, and whether the probability of benefit is greater than the probability of harm.
